FOLDING PAPER CARTON Filed Dec. 28, 1925 3 Sheets-Sheet '3 1 Patented Feb. 18,5193() HENRY E; KONDOLF, F BROOKLYN, NEW YORK FOLDING PAPER CARTON Application led December 28, 192.5. Serial No. 78,019.

This invention relates to an improvement in folding paper cartons, and one of the principal objects thereof is to rovide a carton which may contain an article to be vended, the construction of the carton being such that lthe article contained therein may be inspected, or, where the article requires to be tested, may be tested, while in the carton, but cannot be withdrawn therefrom without destroying the carton, with the result that fraudulent substitution of a defective article for a good one, andY return of such defectivearticle to the vendor, with the plea that the article sold was defective, may be avoided.V A further object of the invention is to provide a carton of the nature above referred to, so .made as 'to 'be capable of being shipped from the manufacturer to the user in flat, folded form,to thereby occupy a minimum of space, such carton being capable of quick conversion from folded to extended or article-receiving condition.

Another object of the invention is to provide. acirton of the nature above set forth, so constructed as to transport its'contents in a condition cushioned against the effect of shocks apd jars in transit or handling.

A further object of my present invention is toprovide a carton, adaptable amongstl other uses, to the safe transportation and fraudulent substitution prevention, of electron tubes.d

In connection with the particular adaptation of the invention here illustrated, the carton is so constructed that the electron tube may be inspected and tested while contained within the carton, and while the carton is in 'sealed'conditiom it being necessary, in order to withdraw the tube from the carton, to mutilatethe latter. The substitution of a' defectivetube. for the perfect tube sold while contained within the carton, would therefore become at once apparent.

.'With these zand further objects inv View,

which will become apparent as the description. proceeds, the invention resides in the construction, combination and arrangement of parts hereinafter more ffully described and claimed.

being flanked by sections 6 and 7 which respectively form the rear and front Walls of Figure 12 represents a fragmentary secbottom of the ,completed carton, such section the carton. Section is connected to section 6 alongthe crease 8- and to section 7 along the crease 9. A

The bottom section 5 is continued at each i endto formA end flaps 10 and 11, respectively,

such flaps being connected with the bottom section along the creases 12 and 13, respectively.' The rear wall section 6, and the front-Wall section 7, likewise are extended as4 at 14 to form partition wall flaps, such partition wall aps being connected to the respective front and rear wall sections along'4 the creases 15. The end flap 10, on one side of the blank is separated from the flanking partlition'wall flaps 14 by c-u'ts 16 which extend the length of the partition wall flaps, and similarly the end flap l10n the opposite side of the blank is separated from its flankingp'artition wall flaps by similar cuts 17.

Along the opposite edge-of the rear wall section from the bottomsection 5 is a cover section 18, such section bein-g connected to the rear wall section aloITg the crease 19. End wall sections 20, form continuations of thecovervr section 18, being connected thereto along the creases 21. The end Wall sections .are se arated from the adjacent partition wall aps '14 ,along the cuts 22. The cover section 18 at its free edge is provided with -an insert ilap ,23 connected with the cover section along the crease 24, and each of the end wall sectionslat its ends is provided with an insert flap 25-and at its outer edgegwith a similar flap'26, such flaps being connected to the end wall sections along the creases 27 and 28, respectively. l The particularexampl'e Iof theinvention yherein set forth, is designed for the accommodation of electron tubes, and invthis form of the invention I- ,utilize the vpartitions formed by the partition Wall flaps, -as hereinafter set forth, tosupport and'carry the tube; and hold it out of contact with the main body walls` of the carton, to thereby cushion and protect it against the effects of `shocks and jars in transportation and in.\handliug.

5 To this end, the partition wall flaps, from which the Ypartition walls are' to be made in the instant illustration, are provided with openings 29in which openings, when the feo.-

partition Walls are 'formed'the base portion and .head portion of the electron tube are reeeived. A An opening 48, also, is provided in-l A. the end flap 11 to snugly receive the prongs or leads of theg tube as will later a pear. The openings 29 it will be note are located centrally of the quadrangular pertions of the partition wall flaps' formed by the three free edges of such flaps, and the creases 30. These creases are arranged parallel with the ends of the aps and are spaced vfrom the creases 15, which connect the rear and front wall `sections with-thepartition walll aps,

"to form hinge portions 31, the purpose of which will b e hereinafter set forth. 1 Longitudinally of thevblank, ji. e., transversely of the partition walls (when formed), the partition wall flaps are creased as at 32, such creases being arranged preferably diametrically with respect to the' openings 29.

Transversely of the blank, i. e., longitudinally of the bottom wall section 5, such sectinA is creasedl as at 33, to allow the bottom wall to fold upon itself as indicated in Figure 2, and extensions 34 of the crease 33, traverse the end flaps 10 and 11, so that the halves' of the end flaps also may fold upon each other, as indicatedin Figure 2.

The end iaps 10 'and y1 1 are creased, as at 35, at right 'angles to the creases 34 and at a distance from the creases 12 and 13, respectively, to thereby form bottom hinge portions 36, upon whichklthe end flaps swing to be disposed inwardly of the ends of the box, yand against the partition walls (when formed) in the positions indicated for instance, in Figure '5. The creases 35 in the end iaps, are spaced rom the creasesl2 and 13 a less distance (by substantially twice the thickness of the material from which the blank is formed), than the creases 30 of the partition wall flaps are spaced from the creases 15, to thereby position the end flaps 10, when the box is in the condition illustrated in Figure 5 nearer the ends lof the box than the partitions, at the same time allowing the end flaps to snugly engage against the partitions along the creases 35.

lVhile the cartons mayif desired be distributed by the manufacturer to the user in blank form, by the latterto be set up, it is preferable to shi them in the formed and folded condition illustrated in Figure 2. In this con-dition o 'f the carton, `the partitions havev been made by sivin'ging the hinge por-- tions 3l in'along the creases 15 and bending tbe partition wall flaps relatively to the hinge portionsalongthe creases 30, then overlap-v ping and gluing `the partition wall iaps of trate, the .formed and folded condition of fold upon themselves alongthe creases34,

the-partitionsA 14 (formed by the partition flaps 14) havingrbeen formed and disposed themselves along the creases 32. Thus in the condition shown in Figure 2, the partitions are folded upon each other along the creases 32, the bottom is folded uponlitself along the crease 33, the end iiaps are folded upon themselves along the creases 34 and the front wall 7 is folded down toward the rear wall 6 being separated therefrom by the folded partitions. In this fiat condition numerous cartons may be shipped in a compact space.

When a carton is to be used, the front and rear walls may be grasped and moved away from'each other, this operation pulling the partition walls out to the position indicated yzo in Figure 3, and also extending the bottomA and the end iaps to the position indicated in Figure 3. The carton then resting upon its bottom may be pressed down to straighten the bottom out in a fiat condition, and the vpartitions may bepulled out to a substantially rstraight position, so that the carton takes the condition indicated in Figur-e 4. In this condition, it will be noted that the partitions 14a are disposed inwardly of the ends of the box, the distance of lthe width of the hinge portions 31, and the carton is ready to receive the electron tube. (Figures 8 and 9 show the tube in place in the box).`

The base' portion 37 of the tube extends through one of the partitions 14a, being accommodated by the opening formed by the registering openings 29 in the partition wall flaps which 'constitute that partition, and the head portion 38 of the tube is similarly ac- 'A commodated in-the opening formed in the.

opposite partition. The diameter of the `open-ing in the partition which receives the base. portion of the tuberis equal to the diameter of such base portion to thereby snugly receive the base of the' tube, and the opening in the partition which receives the lhead of the glass portion of the tubemay' be of the saine diameter if desired as the opening in the opposite partition, providedit is smaller than the largest diameter of the head of the' 'tube, to thereby support it and prevent the tube from being withdrawn through the partition which receives its head portion.

The tube having beenplaced in the cartorr in the manner described,`the end flaps 10 and` 11 are disposed in the position indicated in Figures 8 and 9, the bottom hinge portions aov 36 folding up along the creases 12vand 13, re spectively, and the end liaps 10 and 11 folding with respect to the hinge portions along the creases 35. In this position the hinge por-- tionsV 3g, and the bottom portions of the end flaps 1 and 11 bear against vthe partitions 14 adjacent the bottom 5 of the carton, as indicated in Figure 9, to thereby lock such partitions in position. The end flap 11 folds lthe cover section 18 and Y and further yllbe pulled out forthe lend iap 11 thus serves, 1n conjunction with the adjacent partition, to stay or hold the tube rigidly inthe carton, even though the bulb end of the tube should work out of contact with the opposite partition Wall.

The carton is completed by folding down j folding in the end wall sections 2O.y Durin insert flap 23 of the cover is engaged between t-he front wall 7 and the forward hinge sections 31 of the partitions. The insert flaps 25 ofthe end wall sections are inserted within the carton and bear against the upper faces oft-he bottom hingesections 36, and the insert flaps 26 of the end walls are inserted in the carton, and engage against the forward hinge sections 31. Thus the insert flaps 25 and 26 also aid in locking the partitions and end fiaps in tube-supporting position, aid the end flaps and partitions in strengthening and vrigidifying the carton. Inthis completely formed condition of the box, the three walls and the cover form the sides of the box and the end walls 2O form the ends of the box, the partitions are spaced inwardly from the ends of the carton and support the electron tube, and the end flaps are locked into position, and in turn lock the partitions in position, andY one of such end flaps supports the prongs or leads of the tube, and the other bears against the head portion of the tube'.

The carton is now sealed by the utiliaation of a sealing strip 39 across the junction of the front 7 andcover 18 of the carton, as illustrated in Figlire 6, or as illustrated in Figures Tand 10, a sealing cord 40 may be used. Such cord at its ends is provided with g this operation, the i anchors 41, one of which may be passed through a perforation 42 near the forward edge of the cover section and the other anchorafter the cord hasbeen passed down across the front of the'carton, to bridge the junction between the front wall and the c0\ver,.and afterL having been passed across the bottom 5 and up and across the rear wall 6, may be inserted through a'l perforation 43 near the rear edge of the cover section.

Whatever method is used for sealing the carton, it will be observed that while the end walls 20 and one or both ofthe end flaps may `purpose of inspecting and testing the contents of the carton, such contents cannot be removed without tearing oiitmne or both of the partitions, or otherwise mutilating the carton. Thus when the manufacturer, for instance, of electron tubes, has packed a tube in a carton and sealed the latter, he :will know that the tube cannot be removed, and another tube inserted in itsu -place'and returnedto him, without the mutilation of the seal or of the carton informing him that there has been a substitution. The importance of this will become apparent When it is understood that unfortunately e tube beyond its supporting partition. The

vbase ofthe tube may then be grasped and the tubepulled outwardly through its supporting partition a suiiicient distance to allow the 4insertion of the tubein a testing apparatus. Such position is indicated in Figures 10 and 11. ylhe end flap l0 may be pulled out to allow the bulb of the tube to be observed through' the opening in the uppermost partition wall while the tube is in the testing machine. Whenthe base of the tube is vdrawn` outwardly, the increased diameter of the glass body of the tube will prevent the 'tube being withdrawn beyond a certain position,

but nevertheless the tube may be withdrawn sufficiently for testing' purposes, without mutilation of lthe carton, vby virtue of the movement of, hinge portions Bl'along their bounding` creases, and by further` virtue of the bending of the partition along its central crease 34, as illustrated in Figure 11. In this figure it will 'be understood the cover section hasbeen thrown back for purposes of clearness of illustration.

Thus it'willbeA observed that the partition wall-.and its hinges, while supporting and cushioning the tube against the effects of shock and jar, at the same time a e suiii- 'ciently flexible to allow withdrawal of the tube to a position where it can be readily placed in an apparatus for testing purposes,

i but that complete withdrawalof the `tube is impossible without mutilation of ,the carton.

The foregoing description has been given for purposes of clearness of understanding, and no undue limitations should be deduced therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art. v
